The majority of website traffic is driven by the search engines. Millions of people use search engines everyday to research various topics, buy products, and go about their daily surfing activities. Search engines use keywords to help users find relevant information and each of the major search engines has developed a unique algorithm to determine where websites are placed within the search results. When a user clicks on one of the listings in the search results, they are directed to the corresponding website and data is transferred from the website´s server, thus counting the visitors towards the overall flow of traffic to that website.
If a web page is not listed in the first pages of any search, the odds of someone finding it diminishes greatly (especially if there is other competition on the first page). Very few people go past the first page, and the percentage that go to subsequent pages is substantially lower. Consequently, getting proper placement on search engines is as important as the web site itself.
